@NullVoxPopuli the problem with this now is that if you visit https://e164cf93.ember-toucan-core.pages.dev/, you'll see the CSS not being applied. Do we need to tell Webpack about this by adding a CSS Loader of sorts?

[NullVoxPopuli]

It's possible that https://github.com/CrowdStrike/ember-oss-docs/blob/main/ember-oss-docs/package.json#L167 needs to be expanded to differentiate between js and css.
otherwise, it wouldn't be too farfetched to include ./dist/styles in exports so that both webpack and the css-loader are happy.

it turns out googling exports and webpack together is really hard, due to CJS 😅

Some back and forth with AI suggested using resolve.alias, but that's less fun. may work tho

oh, alternatively, these 3 files could be imported in a js file.
